Leners' Patent No.' camminata Augmral, 186s.

The Schedule referred to in these Letters Patent and making part .yf the same.

To all Iwhom it may concern Be it known thatl, T. S. Lnwls, of Portland, in the county of Cumberland, and State otr' Maine, have .nvented a new and useful Machine for Removing Green Corn from 'the Cob: andlhereby declare the following to be a full, clear, and exact description thereof, which will enable others to make and use my invention, reference being had to the accompanying drawings, forming part of this specification, .in which- Figure l is a top plan of my machine, with the cutter-frame removed.

' Figure 2 is a detail front elevation of the cutterframe.

Figures 3 and'4 are detail front elevations of the Scrapers.

Same letters show like arts.

. The' object of myixrvennouis to produce a. machine for removing green corn from the cob, and also for taking with it that'portion of the milk in the kernels which may remain on the cob after the: kernels have been' cntvfrom the same.

My invention consists-- First, of a device for operating a plunger and follower, in connection with a receptacle for the corn-fears andthe cutters.

Second, it consists of an adjustable cutter-frame, with gauged-kuives thereon. v y

Third, it consists of the adjustable scraper or scrapers;

The operating parts 'of my'invention are Vplaced upon a convenient or proper frame, A.

On the topofthis frame, and moving on proper ways, or tiacksais the carriage B, which' has imparted to it an alternate forward and retrograde movement, by means of th'e crank or other power a, the crank-shaft b, and connecting-rods 0,- attached to the sliding frame at d, all being shown in iig. =1.

The two sides, e j, ofthe sliding frame B move unequally, which is accomplishedby the different lengths of the 'cranks on shafts b, from which, bythe connecting-rods c, as aforesaid, motion is communicated to the sliding frame B.

f travels further and more rapidly than c. j' carries the plunger g, attached to the piece j.

, c carries the follower h, attached by the piece i.

k shows the hopper, or receptacle for the ears of corn.

lis a concave, or groove inthc plate o, leading to the cutter n.v

The ears are forced along lthe groove l to the edge ofthe cutter n, by means of the follower h and plunger g, whichlatter works through a hole in the .follower-h, and through an aperture in the end of the hopper k, as illustrated 'in fig. l.

At every motion, therefore, of the plunger y, an c ar is forced against the edge of the cutter n, 4bywhich the kernels are removed from the lower half thereof,A the kernels dropping down, through the s'pace'm, to a proper receptacle below the said'edge of 'n being just enough elevated above Z tocut and remove suioient of the said kernels. s

The cob is then, by the plunger g, forced along the groove in n. This groove' is illustrated in iig. l.

The kernels on the upper half of the ear are re-A moved by the cutter p, fig. 2, (which device will be hereafte1`"explai11ed,) at the same time.

rlvhe end of the follower h. and plunger g are slightly recessed, in order to receive the stalk or but ofthe ear and retain the same.

In preserving corn in accordance with the approved process, more especiallyaccording to that patented by Isaac Winslow, it isjmdrspensahle to remove es much of the milk of the kernels from the cob as possible, in order to preserve the said kernels in their own juices, and in removing the kernels from the cob,'there is always left upon thercob a small cup or hull, in which much ofthe milk of the grain resides.

In view of these facts, I provide the Scrapers, figs. 3 and 4, whiclrconsist each of two uprightarms,`ris ing from a cross-piece of the flame of the machine, and so pivoted thereto as that they will open and shut, the pieces moving in vertical planes, as will b e vided with the cutters, or Scrapers t, and fig. 4 with `those shown at u.

The pressure these will exertupon the cob, as it is forced through themby the plunger g, is regulated by the adjustable weights lr on. the arms After the cutting is performed, the cob being then forced through one or both of thesescrapers, the milk is thus removed from the portions of the kernels remaining on the cob, and runs into -the receptacle for the kernels, and this without any portion ofthe cob being removed by the cutters, or'the hulls in which the said milk may he. ,I y

After being forced through these, the cobs drop down at w.' :t is the removable and adjustable cutter-frame, litting into the spaces y rlhe knife p is attached to the carrier y, is, placed, when in position, directly over the cutter n, and is adjustable to the different sizes of ears, by the projections, set-screws, and slots, as illustrated at z.

The operation of my machine has been sufficiently indicated iu the foregoing description.

It is evident thatvthe knife 1 may be made xed, and n removable.

' What I claim as my invention, and desire to secure by Letters Patent, is

understoodfrom the said figs 3 and 4. Fig. 3 is pro- 1. The sliding carriage B, composed of the parts e 4. The hopper k, iu combination with the sliding f, and carrying the follower h and plunger g, in concarriage B f e, follower h, plunger g, and knives n p,
